HTTP Headers

[Paya, Ashkan]

Hello,

Can we use/overwrite HTTP headers such as USER_AGENT when invoking methods like 
BlobStore.putBlob() or we need to specify the BlobRequestSigner and use 
HttpClient instead?
For example, if I want to include the HTTP headers in the following operation:


ByteSource input = ByteSource.wrap(“BLAH”.getBytes(StandardCharsets.UTF_8));

 Blob blob = blobStore


    .blobBuilder(“NAME")


    .payload(input)


    .contentLength(input.size())


    .contentMD5(input.hash(Hashing.md5()))


    .contentType("text/plain")


    .build();


 blobStore.putBlob(container, blob);


Should I use the BlobRequestSigner as follows? Is this the right approach?


 final BlobRequestSigner signer = blobStoreInfo.getBlobRequestSigner();


 HttpRequest request = signer.signPutBlob(container, blob)


    .toBuilder()


    .addHeader(HttpHeaders.CONTENT_LENGTH,


        String.valueOf(input.size()))


    .addHeader(HttpHeaders.USER_AGENT, “custom agent")


    .payload(input)


    .build();


 HttpClient httpClient = blobStore.getContext().utils().http());

httpClient.invoke(request);





Thank you,
